Test pin M323.689 — Gauge pin, 6.89 mm Ø, ±0.001 mm, 50 mm length (Metav IndustryLine)

The Test pin M323.689 is a precision reference pin for end-dimension checks and fixture set-up in workshop inspection and assembly tasks.

• Micron accuracy ±0.001 mm
• Nominal diameter 6.89 mm
• 50 mm hardened length
• Workshop version, robust construction

Accuracy that keeps production consistent

A tolerance of ±0.001 mm on a 6.89 mm reference diameter delivers the level of precision required for critical end-measurements and tight-tolerance checks. Such fineness in tolerance reduces the need for rework and supports reproducible setups across shifts and machines. The high stability of the datum reduces measurement scatter, so inspections become a reliable pass/fail decision rather than a repeat exercise, improving throughput and process capability.

Built for daily workshop handling

The workshop configuration balances durability with handling convenience: the pin is manufactured from special steel and designed for robust use in routine inspection or as a fixed reference in jigs. With a 50 mm usable length and a low mass, handling is straightforward while maintaining stiffness where it matters. Delivered in a protective transport box, the item resists transit damage and arrives ready for safe storage or immediate use at the inspection bench.

Simple integration into inspection workflows

The test pin supports quick identification and inventory control through its clear article reference M323.689. As a compact reference gauge, it fits into established measuring sequences and tooling nests without adding complexity, shortening set‑up time and improving repeatability in dimensional checks. The combination of compact form and micron accuracy makes it suitable for batch spot checks, fixture alignment and small-batch quality control.
